Abstract: An FeRAM in which sensing occurs without a dummy cell, using an
unselected bitline as a reference. The read cycle includes two opposed

Abstract: The method involves using a carrier for performing at least one processing step, whereby the disc-shaped object is laid in a larger distance on the carrier by using an instrument, with which the object has been taken from a storage container. The distance between the object and the carrier is reduced for the processing step, is increased after finishing the processing step, and the object is removed again and is moved back into the storage container by using the instrument. The distance between the object and the carrier is preferably controlled through a lift arrangement, formed e.g. as pegs arranged vertically to the surface of the object facing the carrier, which can be projected from or retracted into the carrier.

image sensor. This invention further discloses a CMOS
image sensor that has variable spatial resolution and
bit resolution. Starting as a high spatial resolution
low-bit resolution image sensor, the high
bit-resolution is achieved by combining information
from a group of nearest-neighbor pixels into a single
super-pixel via spatial oversampling. This variable
CMOS image sensor can be used in a multiple function
